Stuff a sock in it! lol, no really, bilge pumps cannot keep up with even the smallest hole. A one inch hole will gush 25 gallons per minute into you boat, you need to slow it down, and fast. I've got a couple of stories, but for know let's just say, two strapping young men with 5 gallon buckets, cannot keep up with a 6" long, 2" wide gash; even with four socks, two t-shirts, and one pair of shorts stuffed in it.
